Abstract
A kind of new type of compression machine stator described in the utility model, when not reducing refrigerant circulation area, reducing the quantity of trimming or reducing the sectional area of trimming, having the opening of appropriate size and quantity in stator faces increase.Trimming described in the utility model is little and few, adds the area of contact of described stator and shell, thus increases the enclasping force of stator and housing.In compressor operating process, pressurized gas and refrigerant gas are improved as present flowing between opening from original by flowing between trimming, thus make this Novel stator under guarantee meets the condition of refrigerant circulation area, greatly improve the Safety performance in compressor operating process.
Description
Technical field
It is rotary compressor field that the utility model relates to field, especially relates to a kind ofly increasing refrigerant circulation area and improving the rotary compressor stator of compressor Safety performance.
Background technique
The stator of rotary compressor is one of pith of compressor inside, that interference fit connects between the stator of compressor and housing, usually first housing being carried out heating makes it expand, and then stator is inserted in rapidly relief, and it cools naturally, thus holds stator tightly.Stator has trimming, to ensure that refrigerant can circulate, in compressor operation, the gas after overcompression flows through trimming and arrives stator upper cavity from stator bottom, then discharge through outlet pipe, the flowing of refrigerant gas flows through trimming from stator upper cavity to arrive stator bottom.In order to meet the requirement of circulation area, stator need cut different limit numbers according to different machines, this inherently affects the area of contact of stator and shell inner surface, and then the enclasping force affected between them, enclasping force deficiency can have a strong impact on the Safety performance of compressor, serious meeting causes stator to be shifted, and stator displacement can affect the efficiency of compressor, if motor end is encountered top cover and also had danger of hazardous electrical discharges when being shifted excessive.Adopt large trimming or many trimmings, this mode can increase refrigerant circulation area, but can reduce the area of contact of stator and housing, affects the enclasping force between them, thus reduces the Safety performance of compressor.
Model utility content
In order to solve the trimming of stator in prior art, stator and compressor housing internal surface area of contact are reduced, affect the problem of compressor stability, the utility model provides a kind of and increases refrigerant circulation area, but does not reduce a kind of new type of compression machine stator of stator and shell inner surface area of contact.
A kind of new type of compression machine stator, described stator inner wall axial distribution has winding wire slot, and described stator has opening, and described opening extends to lower end surface by the upper-end surface of stator.
Described opening is circular, and sectional area is identical.
Described opening has multiple, and each opening is symmetric relative to stator center axle, and each opening is circumferentially same.
Described stator has trimming.
Described opening, two or more openings form one group of opening group, and opening group and trimming interval are arranged.
Preferably, each opening group has four openings.
Described opening is perpendicular to the end face of stator.
Described stator forms by multiple stator piece is stacked.
The utility model is compared with conventional compression machine stator, cylinder has opening, increase refrigerant circulation area, the utility model can not open trimming, or when refrigerant circulation area is identical, trimming area is little, number is few, and stator described in the utility model and shell inner surface area of contact are large, good stability; And due to area of contact increase, the amount of deformation of housing also can reduce.
Accompanying drawing explanation
Fig. 1 is the plan view of stator.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in detail:
A kind of new type of compression machine stator, described stator inner wall axial distribution has winding wire slot 2, described stator has opening 1, and described opening 1 extends to lower end surface by the upper-end surface of stator.
Described opening 1 is circular, and sectional area is identical.
Described opening 1 has multiple, and each opening 1 is symmetric relative to stator center axle, and each opening 1 is circumferentially same.
Described stator has trimming 3.
Described opening 1, two or more openings 1 form one group of opening group, and opening group and trimming 3 interval are arranged.
Preferably, each opening group has four openings 1.
Described opening 1 is perpendicular to the end face of stator.
Described stator forms by multiple stator piece is stacked.
Compared with traditional stator, the utility model has opening 1 on stator, and described opening 1 increases refrigerant circulation area.Described stator does not need the mode adopting increase trimming 3 and increase trimming 3 to increase refrigerant circulation area, adds the area of contact of stator and shell, thus increases the enclasping force of stator and housing; And due to area of contact increase, the amount of deformation of housing also can reduce.In compressor operating process, pressurized gas and refrigerant gas are improved as present flowing between the opening 1 of stator from original by flowing between trimming 3, thus make this Novel stator under guarantee meets the condition of refrigerant circulation area, greatly improve the Safety performance in compressor operating process.
Certainly; more than illustrate and be only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this specification; made all equivalently to substitute, obvious variant, within the essential scope all dropping on this specification, protection of the present utility model ought to be subject to.
